# Associated $Z^\prime$ production in the flavorful $U(1)$ scenario for $R_{K^{(*)}}$

## TL;DR

This paper investigates a flavorful $Z'$ model that could explain anomalies in $R_K$ and $R_{K^*}$ by analyzing its potential signals at the 14 TeV LHC and considering current experimental constraints.

## Contribution

It explores the collider phenomenology of a specific $Z'$ model addressing flavor anomalies, including LHC search prospects and existing limits.

## Key findings

- Constraints from low-energy processes limit the model parameters.
- Potential signals at the 14 TeV LHC are identified in two complementary channels.
- Current LHC dimuon resonance searches restrict the viable parameter space.

## Abstract

The flavorful $Z^\prime$ model with its couplings restricted to the left-handed second generation leptons and third generation quarks can potentially resolve the observed anomalies in $R_K$ and $R_{K^*}$. After examining the current limits on this model from various low-energy processes, we probe this scenario at 14 TeV high-luminosity run of the LHC using two complementary channels: one governed by the coupling of $Z'$ to $b$-quarks and the other to muons. We also discuss the implications of the latest LHC high mass resonance searches in the dimuon channel on the model parameter space of our interest.
